Be it known that I, JOSEPH' 1V. Sononnnn- LEX, a citizen of theUnitedstates, resid ng Improvement in Sheet-Gauging Devices for Presses,of which the following is a specification. Th's invention has to. dowith punch presses by .whichpiecesof suitableform and size are cut frommetal sheets for use'in the making of can ends, or the like, and theparticular improvement provided is for the purpose of properly gauging'the sheetsin their various operative positions as they An importantobject of the gauging dev ce which may be placed upon presses ofstandardform and construction Numerous other objects and advantages I ofthe inventionwillbe apparent as itis .better understood 1 scription,which,

from the following. detaken in connection with the accompanyingdrawings, discloses a preferred embodiment thereof.

- Referring to the drawings, a

Figure 1 isaside elevat on of a standard press upon which a deviceembodying my invention is employed, being partially broken away tobetter illustrate some ofthe operating elements; p

Fig. 2' is a front end elevation, taken substantially along the line2-2'0f Fig. 1; Fig. 3 is a plan viewof the bed of the press, being takensubstantially along the broken line 3-3 in Fig. 1; and

Fig. e is a detail perspective view of the device of my invention, shownapart from the other mechanism.

The general organization of the machine, which has been shown on" thedrawings for purposes of illustration, is well-known and n ed not-be d sribed i P ticular d tai in the county of Weber and State of Utah, haveinvented a new and useful U invention is f theprovislon of a device forthis purpose, which is automatically operable in synchronisin with theof the sheets and the action ofthe'punch; I v V i A further object isthe provision of asheetv tune-, tion without likelihood of breakage, orthe necessity for. frequent repair complicating the structure, or

A frame 11 supported from, base members 12 and has mounted 'in the upperpart thereof a crankshaft 13 which carries a drivingpulley 14,across-head 15-and brake mechanism 16. -An upper slide 17 issuspendedfrom the cross-head 15 andcarries a'punoh .18 adapted ito' cooperatewith a die member (notshowny mounted in a die block 19, whichlnJGU-LEII'IS supported by a ,bolste'r'plate resting upon an extensionbcdplate'22 upon the frame 11. A feeding. table 23is provided abovethe*die :block 19.nnd is supportednat its front end by means of abracket 2a secured to the,

bed plate 22, the rear end of said table being supported ,by means 'of aweb '25] extending; between the sides of the press frame. v I

Referring now in detail to the mechanism provided by my invention, itwill be noted thata short shaft 26 is mounted in bearings 27 and 28secured to the side of the feeding table-23 and is adapted to be rotatedby nean'sj ofa spiral gear 29 meshin with a spiral gear 31Ylmounted onthe end of a' transverse j shaft. 32, which 1s journaled in a bearing33and is driven from the crank shaft 13"by"ineans of a sprocket chain.34 taking over sprockets '35 and 86 mounted respectively onfltheshaft-s" 32 and A plurality ofequally spaced fingers 37 r for a purposewhich will here inafter appear.

'are mounteduponthe shaft 26 and pro- A side guide" 38 is provided uponthe table Qt-land a retaining bar 89 extends laterally therefrom andisadapted toprevent upward displacement of the sheets as they aresuccessively .fed through the machine For the purpose of feeding saidsheets, I employ a described. A short transverse shaft 41 is journaledin a bearing 42'secured to the edge of the table 23 and carries on itstoperiodically engage and advance asheet is accomplished sprocketconnection'with the" shaft 32.

mechanism which will now be" inner end an eccentric 43, which is adaptedc nnection mp es mane taki g over sprocket 4'? mounted on the shaft 18so that the sheet is advanced one step for each stroke of said punch, itbeing understood that the advance takes place while the punch is in itsraised position.

YJhen the sheet is in position for the first cut, its forward edge restsagainst the forward finger 37, which at this time extendsver-ticallydownward and forms a stop accurately ocating said sheet in desiredposition; The shaft 26 rotates in such timed relation thatit makes aquarter turn at each Stroke of the punch and each revolution of theshaft 41. Upon the next feeding action, therefore, the forward edge ofthe sheet is brought into contact with the second finger 37, which. hasby this time assumed the downward position and the sheet is held for thesecond stroke of the punch. Further rotation of the shaft 26 results instopping the sheet at the proper positions for the remaining cuts to bemade (there being in the present instance four cuts in the length of thesheet) and when these are completed, the sheet discharged from. themachine, f: f by gravity to any desired place of s Time the sheets areproperly gauged and brought to restvat the successive operativepositions by wholly automatic mechanism and without the necessity of anymanual handling.

' I t is thought that the inventionand many of its attendant advantageswill be under- "stood from the foregoing description, and

it will be apparent that various changes may be made in the form,construction and arrangement of the parts without departing from thespirit and scope of the invention, or sacrificing all of its material.ad vantages, the form hereinbeforedescribed being merely a preferredembodiment thereof.

I claim:

l. A sheetgauging device for presses and the like, comprising arotatable element arranged longitudinally of the path of travel of thesheets and having a plurality of projections thereon adapted to besuccessively disposedin sheet obstruction position during the rotationof said element, a transverse shaft having a camrto bear intermittentlyon the tops of the sheets, and means connecting said transverse shaftand rotatable element for operation in timed relation to each other.

2. A sheet gauging device forpresses and with punching dies and meansforadvancing sheets of tin plate, or the like, into the sphere of actionof said dies, of a rotatable element having a pluralityof projectionsdisposed along the lengththereof and extending radially-therefrom indifferent directions, said projections being successively projectableinto the pathof a sheet to position it at the variousoperating-positions, and a transverse shaft geared with said rotatableelements a second transverse shaft having a cam for intermittentlypropelling the sheets against said projections, and mechanism operatingsaid transverse shafts and the punching dies. 7

4. Ina press, the combination of recipro eating dies, means comprising acam which bears intermittently on the tops of the sheets for feeding tinsheets, or the like, into the sphere of action of said dies, and meansautomatically operable in timed relation .with respect to theaction ofsaid feeding means to stop the sheet at a plurality of different pointsto permit the takingof successive cuts therefrom in exact predeterminedorder.
